Abstract:
Social network analysis views social relationships in terms of network theory consisting of nodes and ties. Nodes are the individual within the networks. Ties are the relationships between the node which may be people, organization etc. "Social network analysis is the mapping and measuring of relationships and flows between people, groups, organizations, computers or other information/knowledge processing entities" (Valdis Krebs, 2002). Social Network Analysis (SNA) is a analysis for visualizing our people, and identify how we can best interact to diffusion of knowledge. Diffusion of knowledge can happened in social networks due to spreading of items through word of mouth and exogenous factors. These items may be news, videos, and advertisements. We get counseling relationship network and intelligence relationship network basing on the relationship between students in the class and how knowledge diffuses among them. Here we analyse network density, centrality and cohesive subgroup of the network. in this work first we collect data set then we analyze the counseling relationship network and intelligence relationship network.

Keywords: Knowledge diffusion; Social network analysis; Network Structure; network community.
